Arbitrary-view human action recognition via novel-view action generation
作者:
Highlights:
• We propose a two-branch novel-view action generation approach for arbitrary-view action recognition.
• The two-branch generation model generates novel-view action samples, which enlarges the view range of action samples for classifier training.
• A view-domain generalization module is designed to weaken the difference of action representation in various views for the arbitrary-view action recognition.
• Extensive experiments and ablation studies are performed on three large-scale benchmarks, UESTC, NTU-60 and NTU-120 datasets.
